I tested Katya (17.5 intial BG at vet 400, diagnosed 10 days ago) this morning but with a different meter. I bought a ReliOn Confirm (other is a Prime). I tested both of them on me and the Confirm reads higher than the Prime. The Confirm requires less blood (.03). So tested her with the Confirm and it was 142. She had grazed some within the previous two hours. At the vets last Wed it was 196. Anyway she gets dehydrated and also has the neuropathy thing going on so I had asked the vet for Sub Qs and B12. I had a cat with CRF, so I have given Subs before. My main question was that there is a port on the line and rather than sticking her with the B12, could I add it to fluids? Also where can you get the sticks to test ketones?? TY
